Redox properties of extracellular polymeric substances (EPS) from electroactive bacteria
Although the capacity for electroactive bacteria to convert environmental metallic minerals and organic pollutants is well known, the role of the redox properties of microbial extracellular polymeric substances (EPS) in this process is poorly understood. In this work, the redox properties of EPS from two widely present electroactive bacterial strains (Shewanella oneidensis and Pseudomonas putid...
متن کاملComposition and aggregation of extracellular polymeric substances (EPS) in hyperhaline and municipal wastewater treatment plants
As important constituents of activated sludge flocs, extracellular polymeric substances (EPS) play significant roles in pollutants adsorption, the formation and maintenance of microbial aggregates, and the protection of microbes from external environmental stresses. In this work, EPS in activated sludge from a municipal wastewater treatment plant (M-WWTP) with anaerobic/anoxic/oxic (A(2)/O) pro...
متن کاملBiosynthesis of Extracellular Polymeric Substances (EPS) and Its Role in Microbial Biofilm Formation
Microbial biofilm formed on abiotic surfaces is an important area of research because of the wide range of possible affects and the disinfectant resistance of the cells. The colonization of solid surfaces by microorganisms is a very complicated process that depends mostly on extracellular molecule production. The biosynthesis of EPS reflected not only the attachment and aggregation process but ...
متن کاملDistribution and composition of dissolved extracellular polymeric substances (EPS) in Antarctic sea ice
Concentrations and chemical composition of carbohydrates in dissolved organic carbon (DOC) and in extracellular polymeric substances (EPS) from brines, ice cores, gap layers in sea ice and associated surface waters were determined during 2004 and 2006 in the Weddell Sea, Antarctica. High levels of spatial heterogeneity were a common feature in these habitats, with DOC concentrations ranging fro...
متن کاملExtracellular Polymeric Substances (EPS) of Freshwater Biofilms Stabilize and Modify CeO2 and Ag Nanoparticles
Streams are potential receiving compartments for engineered nanoparticles (NP). In streams, NP may remain dispersed or settle to the benthic compartment. Both dispersed and settling NP can accumulate in benthic biofilms called periphyton that are essential to stream ecosystems. Periphytic organisms excrete extracellular polymeric substances (EPS) that interact with any material reaching the bio...
